As a member of several Facebook coin groups, I see 1943 P/D/S replicas and, on occasion, die struck Chinese counterfeits. Yet many new collectors claim to have found these ultra rarities, believing that they struck it rich. They have been informed by click-bait posts and videos telling viewers that these rarities will turn up in rolls and pocket change.
What turns up are replicas, altered dates, copper plated steel cents and die-struck copper counterfeits.
Approximately 40 copper-alloy cents were accidentally minted across all three U.S. Mints (Philadelphia, Denver, San Francisco) in 1943. The 1943-D is the rarest (1 known), while 1943-S (San Francisco) is exceptionally rare (fewer than 5 known). Some 20+ 1943 cents are said to exist.
Types of Fake Coins
Copper plated zinc cents cost less than $10 on Etsy and other sites. These are replicas, as in the photo below.

Chinese counterfeiters have perfected their craft making fake 1943 P/D/S “copper” cents.
Common production methods include:
- Striking on Non-Magnetic Blanks: Counterfeiters use copper or bronze blanks to strike fake coins. Unlike genuine 1943 steel cents that are magnetic, these fakes will not stick to a magnet as if genuine copper.
- Transfer Die Technology: Counterfeiters often use transfer dies, taking a genuine 1943 steel cent and pressing it into a heated, metal to create an exact negative image of the coin. Then they strike copper or bronze copies.
- Copper Plating: Counterfeiters also take common 1943 steel pennies and coating them in a thin layer of copper. These, however, will still be magnetic.
- Date Alteration: Some forgers take genuine copper pennies from 1945, 1948, or 1949 and manually rework the last digit into a “3.”
The latest threat involves advanced operations in China with minting equipment on par with the US Mint.
Simple detection methods include using
- A magnet. If the coin sticks to it, it isn’t copper.
- A coin scale to see if your specimen weighs 3.1 grams. (Steel cents weigh 2.7 grams.)
- A lupe to view the date and to detect if it has been altered.
Here’s an example of a 1948 cent altered to look like a 1943 copper cent weighing 3.1 grams and passes the magnet test:

1943 Copper Cent
A more advanced method to detect counterfeits concerns die markers.
This person claims to have found a 1943 copper cent below. The date on genuine copper and steel cents are the same. Also, on the 1943 cent, the word “liberty” is strongly struck without die deterioration. Here is his counterfeit:

Here’s how to check using die markers:

As you can see, the “9” in the counterfeit is lower than the “9” of the steel an genuine cent.
1943-D Copper Cent
Only one 1943-D Copper Cent has been found. Again, the market is flooded with thousands of replicas and counterfeits.
A genuine 1943-D copper cent would have the exact same date position as a 1943-D steel cent. Because both coins were struck using the same dies, the alignment and shape of the digits must be identical.
This fake was posted on Facebook:

You can see that the date and mintmark differ from the sole authentic one:

The counterfeit is also affirmed when compared with the date and mintmark position of the 1943-D Steel Cent:

1943-S Copper Cent
Genuine 1943-S copper cents are very rare, with fewer than 5 known. Look for faint doubling on the date and die scratches near the motto and wheat stalks.

Another die marker on some 1943-S copper cents is a tilted “S.”

Odds of finding any of these ultra rarities are minimal. Consider the tens of thousands of replicas, altered dates, plated steel cents and die-struck counterfeits as opposed to the handful of genuine rarities that actually have been slabbed. Nevertheless, if you still believe you have one of the dozen or so lost genuine 1943 copper cents, send to PCGS, CAC, ANACS or NGC for the verdict.
